Rapid Charger Introduction The Rapid Charger is a basic charger which converts AC to DC by using a conventional transformer followed by a rectifying circuitry. This charger can consequently not be used worldwide, as opposed to a primary switched charger, and will therefor be available in several different versions as listed on next page. The Rapid Charger consists of: • AC/DC converter incl. wall plug • secondary cord with power connector
The AC/DC converter is plugged directly into the mains power outlet and the rectified DC voltage/current is distributed via the secondary cord to the power connector, which is plugged into the system connector of the phone.
Main Features The Rapid Charger can be used as power source in two different ways, for: • the 7X8-family phones • the DeskTop Charger MC7000

DeskTop Charger MC7000 Introduction The DeskTop Charger MC7000 is a dual desk charger specially designed for the 7X8-family telephones. The phone is placed in the front slot for simultaneous powering and battery charging, while the spare battery to be charged is placed in the rear slot, which also features a manual discharge/reconditioning facility.
As the MC7000 does not include an internal power supply, an external power source has to be connected to the system bus connector at the rear of the unit. The external power source should be one of the following Ericsson product: • Rapid Charger • Travel Charger • Vehicle Power/Charger Furthermore, the Portable HandsFree as well as Mobile Office equipment can be connected to the DeskTop Charger MC7000.

Electronics The electronics of the MC7000 is designed around the Central Processing Unit.
Central Processing Unit The Central Processing Unit (CPU) is equipped with 4kbyte ROM, thus making it possible to control the entire MC7000 charger. The supply voltage to the CPU is +3.8V which is being derived from a linear voltage regulator and a crystal generates a 5MHz clock frequency to the oscillator input of the CPU. The Central Processing Unit interacts with the following major peripheral blocks: • • • • • • •

Supply Current Monitor The current distributed from the external power source to the front or rear slot passes through the Supply Current Monitor. The CPU reads the output from the Supply Current Monitor is order to establish whether charging or charging completed is in effect as follows: >200mA: 200mA
